daniel.gomes what you need is something like this:

Funprog BPC_HAS_NOTES(YBPCNUM)
Value Char YBPCNUM

  Local File NOTE    [F:YNTS]
  
  Local Integer YHASNOTES : [L]YHASNOTES = [V]CST_ANO
  
  Filter [F:YNTS] Where BPCNUM=YBPCNUM
  If rowcount([F:YNTS])>AVOID.AINT
    [L]YHASNOTES = [V]CST_AYES
  Endif
  
  LogicClose File [F:YNTS]

End [L]YHASNOTES

It returns 2 if the customer as notes, and returns 1 if it doesn't.

I haven't tested, but it should work.

Best Regards

Hi ZPMARCOS,

Thank you, for your help. 

I'm new on sage x3 and 4GL development but for testing I create your code on left list of the BPC object and always return 2. Even for customers that doesn't has notes. 

Did I make something wrong?

What I really want is to check if customer has notes when creating or updating an record. 

 "VERIF_CRE" and  "VERIF_MOD" 

Thanks in advance.

Best Regards,

Daniel
