Hi Ray -
Thank you for posting to the forums and using Microsoft Dynamics RMS. We're excited to have you as a customer! Since you are new to RMS, I would suggest speaking with your partner who may be able to provide guidance for your specific business and requirements. However, please find my answers to your questions inline below.
1. I may not understand your question and may need some more details here. When you create a new matrix item, it automatically sets Quantity on Hand to 0. Are you seeing something different?
2. To set up selling commissions, you must open the Item properties page and then choose the Commissions tab. If you wish to bulk edit the items, I would suggest working with your partner to utilize a T-SQL statement that will modify the database directly. However, anytime you edit the database directly, you must be very careful. As mentioned earlier, I would recommend working with your partner on this.
3. On the master item, choose the Component Items tab. In the lower left, choose Filter, and then select only the appropriate sizes you wish to adjust. This will now filter the Component items grid. Next, select the Choose Columns button. From here, add the Cost field and any Price fields you wish to adjust and select OK. You can now edit the component items in the grid.
4. As in 2. above, your only option would be to utilize a T-SQL statement to modify your database directly. Again, I would strongly encourage you to work with your partner on this. Additionally, you could work with your partner for an add-in that may assist you in this setup.
I will also post this in your previous message, but I would suggest you post "how to" questions in our community boards where you'll find others asking similar questions: http://www.microsoft.com/BusinessSolutions/Community/NewsgroupLanding.aspx
I hope this helps.
