Description
This procedure can be used to convert filtering conditions (on browses or reports) on primary key fields into filtering conditions on alternate key fields, which are more readable. This procedure will for example convert a language ID (which is a meaningless number) into a language code. Conversion rules are generated based on the definition of related key business fields in the business class.
Parameters
| tFilter | input | temp-table | input dataset with filter conditions |
| tBusinessFieldValues | output | temp-table | output dataset with converted displayable filter conditions |
| oiReturnStatus | output | integer | Return status of the method. |
