Summary :
When creating or modifying text types and copying rules in the SAP purchasing customization via Transaction OLME, users face the warning message SV019, advising to select a key from the allowed namespace. This occurs due to a design limitation which prevents maintaining entries beginning with 'Y' or 'Z'. In practice, specific text ID conventions must be adhered to, corresponding to document categories. Hence, SV019 can generally be disregarded during maintenance. Important to note, custom text types are not automatically preserved through upgrades or support packages and must be explicitly transported post-upgrade to prevent overwriting by standard configurations.
Key words :
system generates warning message sv019 'choose, ignore warning message sv019, ignore message sv019, maintain entries starting, call transaction sm30, text type f07, existing namespace definitions, standard text types, warning message, message sv019
