Hi Luis,
Parameter IV_UPDATE_BUFFER is not set to' X'.
SAP Reply :
You are directly calling APIs COM_PRODUCT_GUID_GET. It is not
recommended. It will lead to select data from database table.
Please check if there is a way to use BOL entity attributes, without
calling those API.
It is the most painful area.
Thanks & Regards,
