Definition

If this checkbox is marked, at most one filter may be defined in the BAdI definition.

In addition, there are restrictions for the filter expressions in all the corresponding BAdI implementations.

  • At least one filter combination must be specified.
  • As comparator in filter values, only the equals sign '=' is allowed.
  • AND links are not possible.

Use

Limited filter uses make for efficient calculation of the active BAdI implementations that are to be executed at runtime, in particular when there are several active implementations.

A further possible use is the explicit calling of individual implementations. Using the method CL_ENH_BADI_RUNTIME_FUNCTIONS=>GET_IMPLS_FOR_LIMITED_BADI, it is possible to determine all implementations of a BAdI with restricted filter use and then, for example, to have them displayed to the user. The user can decide on one filter value with which the BAdI is then called.

Dependencies

Setting this checkbox is a serious change. Corresponding BAdI implementations can be syntactically incorrect if their filter expressions do not match the above restrictions.

Example

If you have a character-type filter FILT_CHAR defined in a BAdI definition, a filter exprression could be defined in a corresponding BAdI implementation:

    FILT_CHAR = 'ABC' OR FILT_CHAR = 'XYZ'
