Hello Christian .
Your Answer helped me a lot to understand the way to the solution.
Firstly the problem was generated because the XML files were uploaded on the COPY CLIENT environment and this use to cause some problems .
Second after i checked I needed to upload the XML files for SAP CORE 100 V 101 , and on the sistem firstly were uploaded the v 100 witch used to upload DDIC elements and structures that were consistent but couldn't be activated because of the wrong versioning .
After the upload of the right XML version must be checked on all clients on BRF+ for the elements with the status inactive (grey) that belong to the applications created from the upload of the
OPD_EF_PURCHASE_OREDER.XML
OPD_V2_OUTBOUND_DELIVER.XML
OPD_V3_BILLING_DOCUMENT.XML
and delete them .
This resolves all the dumps given on the outputs of the MM and SD modules.
This used to work in my case.
