Summary0042004: Populate table obretco_productcategory causes problems with high concurrency
DescriptionTable obretco_productcategory is populated via ProductListEventHandler.java. This feature was implemented in Issue 30553 for High Volumes. 6 month ago the feature was implemented also to standard WebPOS (not only High Volumes).

The problem appears with high concurrency. For example in an Asynch EDL Process that inserts records in obretco_prol_product. The ProductListEventHandler checks if the product category of the product inserted in obretco_prol_product is present in obretco_productcategory and if it doesn't exists then insert the product category in the table obretco_productcategory for that assortment.

With high concurrency asynchronous processes (running in parallel) two (or more) executions identify the category as missing at the same time and try to insert it at the same time. First one success but subsequent ones produces an: ERROR: duplicate key value violates unique constraint "obretco_productcategory_un"
Steps To ReproduceYou need a process that insert records in obretco_prol_product in paralell with high concurrency. For example an EDL asynch process.

Then try to insert several products with a product category not present in the table obretco_productcategory for that assorment.
