Refinement of the action Create a process and copy the products of the selected ones into it.

Unfortunately I don't understand the logic.
Can you clarify with an example what exactly needs to be done and get the result?

Now this action copies all products from the selected orders, whether you can only copy products of a certain brand or only a certain category from the selected orders.

That is, you need brand and category multiselectors in the action so that when the action fires, apply filtering by them?
If so, then such a revision will take about 2 hours. Let me know if you need an invoice.

Yes, you can issue an invoice, and if possible, add a multi-selector of suppliers.

Will these settings be displayed in the settings of the block itself (to set constant conditions for it)?
Or do you want to be able to select each time in the bulk operations panel before clicking on the "Create Process" button?

It is better, of course, that you can choose in the .panel of mass operations.

The following settings have been added to the block settings:
1. "Display for selection a multi-selector of categories whose products should be taken into account when copying":
Enables the display in the bulk edit panel of a multi-selector of categories, only products of which are taken into account when copied to the created process
If you do not select anything, products of all categories are taken into account
2. "Display for selection a multi-selector of brands whose products to take into account when copying":
Enables displaying in the bulk change panel of the multi-selector of brands, only whose products are taken into account when copied to the created process
If you do not select anything, products of all brands are taken into account
2. "Display for selection a multi-selector of suppliers whose products to take into account when copying":
Enables the display of the multi-selector of suppliers in the bulk change panel - only process products that have a supplier selected from the specified ones are taken into account when copying to the created process
If nothing is selected, products with any selected supplier are taken into account

If you add two such actions (to create different business processes) to the bulk operations panel, then only one BP is created, regardless of which button you press. Can this be fixed?

+

All the same, one process is created, only now not the second, but the one that was first created. And the filters don't work.

The process on which the button was pressed should be created, if there are several of them.

Be specific about what doesn't work. They work according to how it was indicated when the revision was completed.

here is the first setting
here is the second one
when selecting orders and clicking on the first button, the process specified in the settings of the second button is created. All products are added to the process, regardless of the selected settings.
I choose two processes and the category Furniture, it is obvious that two chairs should fall into the process.

the process Invoice to the dealer is created, although it should be according to the settings of the first button Order to the supplier

and all products, not just chairs, get into the process.

if you remove the second setting, the first one works correctly, the filters also work

Check.

Yes. now works. And how many processes can this action handle at a time? Only those that are highlighted on page 1.? If you click Select all (300-400 processes) , will it still process only 1 current page?

Only on the current page according to the selected processes.

And so that all the selected ones can be done?

Yes, you can - it is necessary to modify the logic of the action in the queue of mass changes.
This revision will take up to 1 hour.

let's do, send the bill
