Internal error - An expression services limit has been reached

[MP-iCONN]

I ran into a recent issue with a visual I am creating.  

The Error Message is:
Internal error: An expression services limit has been reached. Please look for potentially complex expressions in your query, and try to simplify them.. The exception was raised by the IDbCommand interface.

Now I believe I have know the reason why it is occuring (due to a column I created) but unsure how to fix.

Basically I have to custom columns.  One called Neg Col will check for all on hand quantities of an item and subtract from the backlog quanity.   This will result in a negative or positive number.

Neg col =

RELATED('Item'[IMA_OnHandQty]) - 'Sales Orders'[Backlog Qty]

Now if I just add that Neg Col this works but once I add my next column it gives that error.

This colum is called Enough Col as seen below. 

Enough Col =

IF([Neg col] >= 0,"Yes","No")

Now if the Neg Col is greater than or equal to Zero it puts Yes, if not it will put a No.

For some reason that Enough Col when added prevents the visual from showing.

Any idea? 

Thank you for any help on this!

Hi @MP-iCONN ,

To work around this issue, rewrite your query. Reference fewer identifiers and constants in the largest expression in the query. You must make sure that the number of identifiers and constants in each expression of the query does not exceed the limit. To do this, you may have to break down a query into more than one single query. Then, create a temporary intermediate result.

You may try add the Neg Co /Enough Col column in Power Query by using "Merge"...
