Prompting a list of all customers defined in Sales Ledger (or Account Receivable as its also known) is simple from within any JBA RPG program.
A call to SL016 - JBA Customer Inquiry - pops a window up, you select you customer using various subset, selection functions and it will be returned to the calling program via the *LDA
Sample RPGLE code could be:
L#CUSN is the returned customer code defined at:
D L#CUSN 482 489
And you can display the customer selection window like this:
// If customer prompt has been requested, do so. // Note: oslsl* needs to be in *libl /free CUSN L#CUSN = CUSN?? IF *INKD; Out LDA; Call 'SL016'; // or whatever prototype you have created to call this RPG*PGM In LDA; CUSN?? = L#CUSN; //populate the return customer number EndIf;
Obviously the Selected customer code is returned via *LDA variable L#CUSN (defined earlier) and in this case you can see that the window looks like this:
