Causal Estimate - BufferOverflow

Hi all,

We are using CausalEstimate function (RPAS: 16.0.1.52, RDF: 16.0.1.50) with several Source Levels. For one of them which is defined at Subcategory/Region Level we get the following Warning:

There are 92 Regions in total and 60 Subcategories. In addition, in the above screenshot scat:365 has 309 Skup in total and rgn:1_1 has 416 Stores, meaning 128544 Skup/Store combinations.

Questions:

1) Does the group lost item count refers to Skup/Store combinations?

2) How does the BufferOverflow warning affects the quality of the final results?

3) Is there any other approach we could follow to avoid this BufferOverflow issue?

Regarding the rest of the parameters:
