How to split multiple items separated by ',' into rows and lookup separated values in reference table

mmvardeleon — Sat, 06 Feb 2021 11:02:10 GMT

I have below script. The fields that need to be split are responsible party, product impacted and region impacted. After slitting, we need the values to lookup in the lookup table. I tried using subfield, and it separated my items, however, I'm unable to look it up in the lookup table.

ErrorLog:
LOAD
ErrorId
,ProcessQueueID
,LinkProcessID as 'LinkProcessIDError'
,[Error Status]
,date([Error Create Date]) as 'Error Create Date'
,date([Error Close Date]) as 'Error Close Date'
,[Caught Before Release]
,ApplyMap('UserMap',LoggedBySID,LoggedBySID) as [Logged By]
,[Caught By Group]
,[Responsibility - Prod]
,ApplyMap('UserMap',QualityVerifier,QualityVerifier) as 'Quality Verifier'
//,[Responsibility - Verifier]

//,[Product Impacted] //multiple selections
,If(Right([Product Impacted],1) = ',',Subfield (Left([Product Impacted],len([Product Impacted])-1),','),Subfield([Product Impacted],',')) as 'Product Impacted'

,[External Team]

//,[Responsible Party] //multiple selections
,If(Right([Responsible Party],1) = ',',Subfield (Left([Responsible Party],len([Responsible Party])-1),','),Subfield([Responsible Party],',')) as 'Responsible Party'

,[Error Description]

//,[Region Impacted] //multiple selections

is this the part where you are encountering your challenge?
If(Right([Region Impacted],1) = ',',Subfield (Left([Region Impacted],len([Region Impacted])-1),','),Subfield([Region Impacted],','))

i think the if statement will always give you the same value in any test case. if i understand it corrcetly the expression is doing the following:
if the last character in the field is a comma, get the subfield (first phrase before a comma) else get the subfield (first phrase before a comma)
so whether the lastchar is a comma or not youre actually getting the same subfield so it doesnt make sense to me.

is the content of the field [region impacted] multiple regions separated by comma? and you want to split it? did you just want the first region or all of the regions?

Maybe like this?

LOAD SubField([Inventāra Nr.], ';', IterNo()) AS Inv.Numurs, SubField([Sērijas Nr.], ';', IterNo()) AS Sēr.Numurs while (len(SubField([Inventāra Nr.], ';', IterNo())) + len(SubField([Sērijas Nr.], ';', IterNo())))>0;
