ranksort retutns no result at item intersection

Hello dear experts!

Need to find several top items in each class by preprocessed sales in RDF. Use ranksort function.

When output measure has weekitenstr_ intersection the function works, but when output has item intersection it returns 0 result.

From rpas config guide:

Rank <- ranksort(WpSlsU, "descending", [prod].[clss])

– If Rank has a base intersection of sku, the result of this procedure is the integer value representing where each SKU’s Sales units ranks amongst all SKUs within its class.

[rpas1502@srv-co-rpas IF]$ printMeasureInfo -d .. -measure totadjbasesls -popcount

  Measure info for 'totadjbasesls':
