please tell me what we mean by Z Transaction in SAP?
DWARKESH THAKKAR replied
Y OR Z these are two latters which sap is provied to create cutomers/ clients own transaction. Same way any Y or Z tables are also not standard they are also created by client. And as and when SAP release any updation in program they will not update any program or table which starts with Y or Z. SAP is not resposible for the Y / Z.
