Summary :
When transferring a DataSource from Business Content or using transaction RSO2, a warning may occur regarding the even-length DEC fields which could lead to issues, such as the display of message R8569. Additionally, using such DataSources can cause a 'DBIF_RSQL_SQL_ERROR' short dump when loading data to the PSA. This is due to DEC, CURR, or QUAN fields having values that exceed their defined length after database operations in BW environments. To resolve, ensure field values do not increase post-manipulation, adjust the field length in the DataSource, or utilize a custom append with an appropriately sized field.
Key words :
internal abap type 'p', 'dec' ddic type, short dump 'dbif_rsql_sql_error', dec field <fieldname>, load extracted data, relevant dec field, highest odd length, numbered length, data extraction, field types
