Query Drilldown does not Invoke Customer Exit Variables

We have a problem with performing a drilldown in a BEx Analyzer reprot, basically the client is a Trading company and they have inter company trading. We are using the Profit Centre as one of thre u201CFree Characteristicsu201D in the query and hence we are able to drilldown on a Characterictc by Profit Centre.

We are using a couple of BEx query variables (Customer Exit variables) to determine the inter-area and extrenal area profit centres and these profit centres will be different based on the level of Hieracry node selected when the query is initially executed. For example if we assume a hierarchy with has one root node, 3 children under the root node and 2 grand-children under each of the 3 child nodes, now if we are at the root Node of the Hierarchy then every profit centre is internal and there are no external profit centres, similarly if we are at the 2nd node (i.e. one of the child nodes) then everything under that node is internal and everything in the other 2 child nodes is external and so on.

This is where the issue starts for us, since on the report if we select the the node we want to see the results for at the query rumtime (i.e. the Customer Exit Variables are invoked at I_STEP=2 and they select the other nodes of the hierarcy if any and group them into either external or internal) then the results are correct. Now if we were to drilldown, i.e. We selected the root node and we drilldown on to see for example of the child nodes then the result are not correct, this becomes apparent when we drilldown further to the grand-child nodes.

One logical explaination is that when we are doing the drilldowns the customer exit variables are not being invoked in the BEx analyzer report and hence they are not grouping the sums for the internal and external profit centres relevent to node selected in the Drill down.

Does anyone have any suggestions regarding how to make this query work properly or show the correct results in BEx Analyzer (ideally), I have considered the Workbooks option but the client does not want Workbooks.

Please let me know if there is a program etc we can customise to ensure that the Customer Exit variables logic is used when the user does a drilldown in the query or any other way to make it work.

Many Thanks
