Generating a forecast in LIS Planning



LIS Planning issue - really stuck and would appreciate any help.

Created new infostructure to hold forecast and demand plan, with new planning type against it.

Copied sales history into sales order qty key figure.

Used macro to copy this data over to Sales Forecast key figure.

Created Activity "prognose" to generate future forecast in Sales Forecast key figure.

Problem - no forecast is being generated - SAP states (when I run the forecast interactively) that there is no historical data available - yet if I SE16 the infostructure I can see the data in the past.

Can't see where SAP is told to look for the historical data - made assumption that it uses the field it is forecasting, but this makes little sense as an ex-post forecast will generally use sales as it's basis, and forecast in a different key figure.

Am I missing something fundamental? Are there any LIS planning experts out there who can help a desperate man?

Any help appreciated.
