0WBS_ELEMT - Error with conversion routine

Hello friends

We are on 7.4 version and facing an error while loading data in BW.

Characteristic value 'J888.0094' of characteristic 0WBS_ELEMT is not WBSEL-converted

Error is coming for only those WBS element that starts from "J888" rest all are loading successfully. When i look into the Master table PRPS i found that these WBS are stored in internal format (without the dot ex- J8880094 rather than J888.0094) but this is not the case with other WBS. Therefore, same values are found in 0WBS_ELEMT master data.

Are the BW loads failing because transaction data cannot co-relate to Master?

Any other suggestions will be appreciated.

Thanks

SK
