I have problems of automatic detection of a picture being present in in a record set. I would like to have a boolean show, if there is a picture present. as I am new to Navision, I tried FlowField Calculation, but the functions available don't seem to fit my needs.
Can anybody help.

    You could try the HASVALUE command

    Syntax: Boolean := Record.BLOBField.HASVALUE();

    (I can't remember whether or not you need to do a calcfields first... eg. Record.CALCFIELDS(BLOBField);)

    Hope this helps you out a bit.
    This isn't a signature, I type this at the bottom of every message
