DDIC Declarations 

A range of structure and table definitions is required in the maintenance interface. When these relevant DDIC objects are declared, the following applies:

●      The starting point for an own implementation of a runtime and maintenance class is a data model in which at least one specialization table for TBRF150 has been created.

In the following, class CL_VALUE_REQUEST_TABLE_MNT_BRF is used again. In turn, this class uses the tables TBRF142 and TBRF144.

○       TBRF142 is displayed on the subscreen as a structure

○       TBRF144 is displayed in an SAP List Viewer

●      The screen structure for TBRF142 is SBRF142.

This screen structure SBRF142 is set up as follows:

○       It includes TBRF142

○       It contains complementary text fields and other additional information

●      The screen structure for TBRF144 is SBRF144.

This screen structure SBRF144 has the following effect:

○       It includes TBRF144

○       It also contains some complementary text fields

●      With TBRF144, the following additional table types exist

○       SBRF144_T

This table type is based on screen structure SBRF144.

SBRF144_T is used for the declaration of the following member tables:

■       DT_BRF144 (MT_BRF144_SCR)

○       TBRF144_T

This table type is based on TBRF144.

TBRF144_T is used for the declaration of the following member tables:

■       MT_BRF144_OLD

■       MT_BRF144_CUR

 

Example: 'Structure-Like' Table TBRF142

In the following table, using the "structure-like" table TBRF142 as an example, you can see:

●      Typical objects derived from the table (column DDIC)

●      Use of the derived object in the maintenance class

●      Use of the derived object in the associated function group

●      Use of the derived object in the runtime class

'Structure-like' means those tables whose entries are not displayed in an SAP List Viewer in maintenance of a BRF object.

 

DDIC	Maintenance Class	Function Group	Runtime Class
TBRF142	MS_BRF142_OLD TYPE TBRF142	Not relevant	MS_BRF142_OLD TYPE TBRF142
TBRF142_T = Table type (TBRF142)	Not relevant	Not relevant	Not relevant
SBRF142 = TBRF142+X	DS_BRF142 TYPE SBRF142 (MS_BRF142_SCR TYPE SBRF142)	TABLES SBRF142. Screen elements: SBRF142-*	Not relevant
SBRF142_T = Table type (SBRF142)	Not relevant	Not relevant	Not relevant

 

Example: 'Table-Like' Table TBRF144

In the following table, using the "table-like" table TBRF144 as an example, you can see:

●      Typical objects derived from the table (column DDIC)

●      Use of the derived object in the maintenance class

●      Use of the derived object in the associated function group

●      Use of the derived object in the runtime class

'Table-like' means those tables whose entries are displayed in a table control in maintenance of a BRF object.

 

DDIC	Maintenance Class	Function Group	Runtime Class
TBRF144	Possibly local declarations	Not relevant	Not relevant
TBRF144_T = Table type (TBRF144)	MT_BRF144_OLD TYPE TBRF142_T	Not relevant	MT_BRF144 TYPE TBRF144_T
SBRF144 = TBRF144+X	Possibly local declarations	TABLES SBRF144. Table columns: SBRF144-*	Not relevant
SBRF144_T = Table type (SBRF144)	DT_BRF144 TYPE SBRF144_T (MT_BRF144_SCR TYPE SBRF144_T)	DATA GT_BRF144 TYPE SBRF144_T.	Not relevant
