bedrock.hier.create.fromsubset - error line 29 / 40

Describe the bug
In the process bedrock.hier.create.fromsubset, lines 29 and 49

CellIsUpdateable( sattrDim, pTgtHier:vElement, sAttrName) = 0

should be replace with

CellIsUpdateable( '}ElementAttributes_' | pTgtDim, pTgtHier:vElement, sAttrName) = 0

To Reproduce
the source dimension has no hierarchy. We use a rollup from this dimension to create a hierarchy on another dimension.

sAttrDim = '}ElementAttributes_' | pSrcDim;
so pTgtHier:vElement will generate an error as the pTgtHier does not exists on the source dimension.
