When a client is selected (while issuing a document), it is possible to execute SQL code.

This is set in Settings-> Purchases / Sales-> Customer’s, run SQL.

After selected by the client user, the variables sent by emdi to the sql code

: cd Line number of document type “eidhpar”.”Aa”
: rd Related document “eidhpar”.”parallhlo”
: pd Parent document “eidhpar”.”Koino”
: cl Customer Line Number “pelates”.”Aa” or “pvlhseis”.”Kvdikospelath”

EMDI accepts the content from the variables and defines it corresponding
