Formulas and formula parameters are maintained in Customizing - Work center:

• Formula parameter in Define formula parameters for work centers

• Formulas in Define formulas for work centers

You must define formula parameters that you want to use before you create formulas, if you do not want to use formula parameters that have been defined by SAP.

You use an indicator to determine where the formula should be used, for example in scheduling and costing.

• There must be at least one space between operand and operator. Exception: brackets in a function, for example, SIN(A).

• Formulas use the same syntax as the ABAP statement COMPUTE. For further information see ABAP User’s guide in the Basis documentation under Numerical operations.

• Units are converted automatically.

If you want to take splits into account in a formula, you must explicitly enter the split in a formula parameter.
