Input Item:

Each input item has one or more input alternatives assigned to it and one of these input alternatives has the S tandard Alternative indicator set for it. A component type is assigned as a role to each input item (for example, an active ingredient or catalyst).

You can assign a substance item (such as a real substance) and a material item or several material group items to each input alternative.The material that is selected first when creating a material group item is the default material .

Output Item:

Each output item has one or more output alternatives assigned to it and one of these output alternatives has the S tandard Alternative indicator set for it. A component type is assigned as a role to each output item.

Furthermore, you can assign a composition list to each output item, as long as an output substance exists for this output item.

Output alternative

You can assign a substance item (such as a real substance) and a material item or several material group items to each output alternative.The material that is selected first when creating a material group item is the default material .

Standard explosion

For the output alternatives you can use the S tandard Explosion indicator to specify that the substance is exploded by default from the existing formula.(The indicator must be set for one output, in other words, if a material or substance is an output of several formulas, you may only set this indicator for the material or substance in one formula.If a substance has been assigned to a material, you may only set this indicator for the substance and the material in the same formula.)

Composition list

You can assign a composition type to the composition list. Each composition list has one or more composition components assigned to it and each composition component is assigned a listed substance.

Repeating Groups

Repeating Group Formula (FORM)

The repeating group formula uses the current substance in the selection criteria to determine all formulas in which this substance occurs as an output substance (real substance of the output alternatives).

When defining the repeating group you can use the Standard Explosion indicator to specify that the substance is exploded by default using the existing formula: If you set the indicator, the system only takes formulas into account in which the Standard Explosion indicator has been set. If you do not set the indicator, the system only takes formulas into account in which the Standard Explosion indicator has not been set.

The syntax depends on how the formula report is generated:

If you access the report by means of a formula (formula report), the formula data is output, as well as the data of the formulas that belong to the various input substances (real substances of the input alternatives) of this formula if necessary.

In this case, the repeating group formula has to be a slave group under the repeating gro up input substances (LORS_IN).

If you access the report by means of a substance, the data is output for the formulas in which this substance occurs as an output substance.

In this case, the repeating group formula must be at the top level of the repeating groups for the formula data. The repeating group formula can either be at the top level of a series of nested repeating groups or below a component repeating group (S:POS, S:POSD).

Repeating Group Recursive Formula (FORMREC)

The repeating group recursive formula works like the repeating group formula but with the following difference: After the repeating group recursive formula has found a formula, for all input substances of the formula, it automatically searches for those formulas in which these input substances occur as output substances. The search is canceled as soon as the system cannot find any more formulas or as soon as it finds formulas that already exist as “parents” in the explosion hierarchy. This means that loops can be avoided.

When defining repeating groups, you can specify the following parameters:

Recursion depth

Specifies the number of recursion levels the system uses to search for the formulas for the input substances.

Standard Explosion indicator

Specifies that the substance or material is exploded by default using the existing formula: If you set the indicator, the system only takes formulas into account in which the Standard Explosion indicator is set. If you do not set the indicator, the system only takes formulas into account in which the Standard Explosion indicator has not been set.

Component type

Specifies which input substances are to be output with which component types (for example, only active ingredients) in the recursive search.

Standard Alternative indicator

Specifies that for the formulas that are found, the system only searches for more formulas, in which the Standard Alternative indicator has been set for the input substances.

Repeating Group Input Substance (LORS_IN)

The repeating group input substance determines all the input items for the current formula in the selection criteria.

When defining repeating groups, you can specify the following parameters:

Standard Alternative indicator

Specifies that the system only outputs the input substances for which the Standard Alternative indicator has been set.

Component type

Specifies that the system only outputs input substances to which a particular role (for example, a basic material) has been assigned.

You can insert the repeating group input substance at the top level of a series of nested groups or below a formula or recursive formula repeating group .

Repeating Group Input Material (LOM_IN)

You can insert the repeating group input material as a slave group of the repeating group input substance at the same level as the input substance repeating group. Therefore, the repeating group input material is either below a formula or recursive formula repeating group or at the highest level of a nested series.

If the repeating group input material is below an input substance repeating group, it selects all input materials (group items) for the current input item.

On the other hand, if the repeating group is not below an input substance repeating group, it selects all input material items for the current formula in the selection criteria.

When defining repeating groups, you can set the Default Material indicator. This ensures that for each input alternative, the system only outputs the input material that is also the default material.

Repeating Group Output Substance (LORS_OUT)

The repeating group output substance determines all the output items for the current formula in the selection criteria.

When defining repeating groups, you can specify the following parameters:

Standard Alternative indicator

Specifies that the system only outputs the output substances for which the Standard Alternative indicator has been set.

Component type

Specifies that the system only outputs output substances to which a particular role (for example, a basic material) has been assigned.

You can insert the repeating group output substance at the top level of a nested series or below a formula or recursive formula repeating group

Repeating Group Output Material (LOM_OUT)

You can insert the repeating group output material as a slave group of the repeating group output substance at the same level as the output substance repeating group. Therefore, the repeating group output material is either below a formula or recursive formula repeating group or at the highest level of a nested series.

If the repeating group output material is below an output substance repeating group, it selects all output materials (group items) for the current output item.

On the other hand, if the repeating group is not below an output substance repeating group, it selects all output material items for the current formula in the selection criteria.

When defining repeating groups, you can set the Default Material indicator. This ensures that for each output alternative, the system only outputs the output material that is also the default material.

Repeating Group Composition (COMP)

The repeating group Composition determines the components for the output substance determined by the selection criteria.

The repeating group Composition is a slave group of the repeating group Output Substances

User Exits

A user exit is created for each formula repeating group in Customizing for Basic Data and Tools in the IMG activity Manage User Exits . The user exit is used to select objects in the repeating groups. One user exit category (GEN_FORMRG, GEN_FORMRC, GEN_LORSIN, GEN_LOMIN, GEN_LORSOUT, GEN_LOMOUT, GEN_COMP), one user exit name, one user exit function module, and the reference function module (copy template) are entered for each user exit.

Syntax Graph

Each repeating group has a unique environment identifier (LENID). For more information on the standard repeating groups (M, D, G, and so on), see Repeating Groups .

The following environment identifiers and possible subsequent environment identifiers have been specified for the formula repeating groups.

The following preceding environment identifiers can exist for the environment identifiers:

The repeating group S:COMP must always be preceded by a LORSOUT repeating group.An EXIT, G, or P group may exist between them.
