Mr Larin, but when i put the statement wait wind refno, it retrieve the same refno for example form A I see refno is RCT0001, form B refno is RCT00001
Once i press the save button in form A, The refno is change to RCT0002. But the form B still maintain the same refno = RCT0001, Therefore I put the code into the save button, I go to select syspec, store refno to tt_refno and increase it to 1, It does work what i expect. wait wind it come the same refno RCT0001
then save it , It come out the same document
