Error Message occurs after loading master data into InfoObject 0DOC_CATEG (SD Document Category) as a result of duplicate data records in the PSA

Hi experts,

I would like to load the master data from the DataSource 0DOC_CATEG_TEXT (SD Document Category) into the InfoObject (InfoProvider) 0DOC_CATEG.

The problem ist that the following error message occurs after I loading the data from DataSource/PSA to InfoObjet per DTP:

In the PSA table of DataSource 0DOC_CATEG_TEXT there are DataSets with keys which differentiate with the upper case and lower case key field. For example "D" = Item proposal and "d" = Trading Contract):

There are anys proposals to load the master data from DataSource to InfoObject 0DOC_CATEG successfully?

Many thanks in advance!

Best regards,
Michael
