Variable in PO Cover Page Text is not appearing
I have a problem in Purchase Order cover page text (document title for email). It can be found in PO trasaction -> Message -> Communication method - Cover Page Text. In the cover page I wrote "Purchase Order Number: &EKKO-EBELN& ". Actually it should come in the email subject with the PO number. It is working fine in one client like "Purchase Order Number: 1234567890". But in the other client it is displaying only "Purchase Order Number:", but value of &EKKO-EBELN& is not coming. What is the reason behind this. Please throw some lights on this issue.
PS: I am using SAP standard program SAPFM06P as print program, modified script and medium as 5-External Send.
Tcode NACE - select application EF - click OUTPUT TYPES - chose the one that is in use for your PO
then go to DETAILS
In the general data folder, on bottom, you assign program and routine for REPLACEMENT OF TEXT SYMBOLS:
SAPMM06E + TEXT_SYMBOL_REPLACE
See then in which task the content is saved and move it to the client where the substitution fails.
