As this is a practical test, and use in anger for first time Monday, I would like to restrict the records to only part numbers commencing 05. So part numbers like 0506CH1288 and 0512THC234 etc, no other records at this time (but want to revert later).
Do I do this in powerapps and if so at the browse gallery level or do I do this at SQL or something else?
If your expression/formula doesn't have any errors, that's a great opportunity to select "Format" just below the expression bar (where you type in the expression). Any changes to an expression after it is formatted, become relatively easier. Just know that the format option is disabled if the expression has errors. So get to a point where there are no errors (even if it's not complete) and then keep adding on to it. Let me know if this helps.
