Summary :
In SAP systems, there are restrictions with Boolean formulas using POSID in PS validations or substitutions. As of Release 4.6, users cannot save validations involving comparisons like PRPS-POSID LIKE 'A*' or substring accesses. This limitation, caused by a programming error, prevents the use of the WBS element's external display format with LIKE or as a sub-field. For systems with Release 4.6B SP 20-21 or 4.6C SP 11 encountering message GB506, the proposed fix involves implementing advanced correction instructions. Users requiring sub-field or LIKE functionalities with the internal WBS number should consider user exits, referencing Note 77268.
