Is this for a single record or for a set of records? If it's for a single record, you'll do something like this:

If {MyTable.TargetQty} <> 0 then {MyTable.AvailableQty} % {MyTable.TargetQty} else 0

There are a couple of things to note about this:

- The initial check for target qty > 0 prevents a divide by 0 error
- The "%" operator automatically does the divide then multiply by 100 to calculate a percentage.

If this is for a set of records, you'll use the "sum()" function. If you're looking for a grand total, you'll just pass the field to the function - sum({MyTable.MyField}). If you're looking for a subtotal based on a group in your report, you'll need to add the group field (which MUST match a group in your report!) - sum({MyTable.MyField}, {MyTable.GroupField}). So, your formula will look something like this:

If sum({MyTable.TargetQty}, {MyTable.GroupField}) > 0 then sum({MyTable.AvailableQty}, {MyTable.GroupField}) % sum({MyTable.TargetQty}, {MyTable.GroupField}) else 0
