Thanks for your answers DBGuy and Gemma but tt was something else.
While away from the screen and walking the dog (which always leads to the solution of the problem at hand
), it came to me: the user must have had the report open on screen while, in an another form, the batch creation of the pfd's was kicked-off.
The solution to this so called "strange behavior" in code?
- check whether the report is open
- if so, close it
- run the report with the parameters wanted
Thanks again for taking the time.
