Hi, we have some problems with the automatic procurement in OpenERP v7.

All our products are of type "make to stock", stockable products, and procurement method is buy or manufacture. For some of them we defined reordering rules, suppliers, boms to avoid getting exceptions for the procurement.

1.) When we install the just in time module (module_mrp_jit), neither manufacturing orders nor purchase quotations are generated. All of the virtual_available counts stay less than 0. Nothing happens.

 2.) When we don't use this module, the scheduler doesn't work, too. All scheduled actions have a count of "-1" and never get triggered. When we activate the mrp scheduler and set the count to 100, everytime it gets triggered, it counts down -1, so it will stop at a count of "-1".

2.1) Warehouse -> Run Schedulers manually doesn't work, too.

3.) The only thing that works, is to go to the product form and press the "Request Procurement" Button. Then all manufacturing orders and quotations are generated.

the timezone of the server is UTC.

so what are we doing wrong? Thanks.
