    Hi thomas_raphael , if you are trying to add a new column, you could consider using Power Query to perform this function.  It may be easier to see the results.

     

    Please note that SEARCH("RunID",Incidentes[Description3],,BLANK()) will return a number representing the starting position of the text.   "Find Text Value"  - if I use search to find "Text" the result will be 6.  If the search fails, the result is BLANK().  You may need to change the BLANK() to either 1 or 1000.

    This result could be passed to the second VAR function.  But it will only find position of the first "," after this start positon.   1, 6 or 1000.  It there is no "," is returns BLANK().

Yes I want to convert from string to integer
 
This is query TExportDataMS_Daily[_Gr]
_Gr = LOOKUPVALUE(MProduct[Size],MProduct[IDProduct],TExportDataMS_Daily[ProductID])
 
 
And when I tried this query I got this isue
_Gr_Numeric = CONVERT(LEFT(TExportDataMS_Daily[_Gr],LEN(TExportDataMS_Daily[_Gr])-1),INTEGER)
 
An argument of function 'LEFT' has the wrong data type or has an invalid value

Hi Anonymous - 
The LOOKUPVALUE function can return any data type (https://dax.guide/lookupvalue/) 

LEFT is a Text function - https://dax.guide/left/.

This will not work when the Product Size if the size is Number.  You need to convert this Number to string https://dax.guide/convert/ before using LEFT. 

But at this stage the function is become complex so it not clear what you are trying.  Can you provide example of the data and expected result?
