Rejecting pallets which can not be filled yet would result in the transporters constantly juggling around pallets until eventually the items for one are available.

Maybe have a look at the opportunistic combiner model Jason Lightfoot posted a couple years ago.

Instead of having the logic constantly search for all possible combinations, each waiting pallet would create a token to check for its requirements. Once they are fulfilled, the transport to a combiner for that pallet could be started.

but one problem I am facing is I have different items type and by using global table I want to match the batch & item arrivals

but I am getting some errors.

It seems I misunderstood your goal. I thought the combiner was not to receive any items, if the pallet couldn't be filled.

Your "Type" labels are numbers, so the code is trying to, for example, read the 105th column. Convert them to strings (either the labels themselves or when reading from the table) to access the correct columns. The deprecated commands you are using do not support strings as row/column references. They will have to be replaced.

Also, the "ItemArrivals" table was not starting with the same numbers as are produced by the source.
