Summary :
SAP Note specifies that maintenance of formula variables for non-numeric fields was not originally included in the formula interpreter. From Release 4.5A, support was extended allowing numeric results from non-numeric field formula variables. User exits prior to 4.5A can define formula variables using an ABAP FORM pool, specifically citing the delivered FORM pool RGSVU000 for custom modifications. Users must manage variable values explicitly within the user exits using a structured internal table var_memory_tab to capture runtime variables and ensure proper global memory management outlined with specific ABAP/4 coding instructions for updating globals.
