Re: Populate parts



Erik,

Thank you for taking the time to put together such a thorough answer.  I'm beginning to get it.
Since the expense_accno_id column is not set to NOT NULL, should I assume that it is not required and should be left as NULL?  Or, should a new expense account be created?  (Sorry, this still not clear to me.)

Thanks.
Brian

Hi Brian,


Regarding the accounts to be used: you should be able to work with the standard income accounts. If you want to differentiate between different types of income, that's when you start creating multiple income accounts. So, you should be able to work with 4010. The Purchases 5010 account doesn't work: the account should be used for things bought. This is not what happens with the parts. Let's consider an example.

You buy 500 items of part p10. Your buying price is 1$ each. So, immediately after delivery of the items you have paid 500$. These 500$ have been turned into inventory, but you didn't actually earn anything yet. Say your selling price is 2$ and you have a single customer who buys 100 items from you every month.

Now, using the "Cost of goods sold" (COGS) method what happens is this: every month you sell 100 items, leading to 200$ in earnings. At the same time your inventory is reduced by 100$ because you're transferring inventory to your customer. The reduction in inventory is accounted for in your PNL as expenses on the COGS account. The result is that your profit (earnings minus cost) are 100$ each month.

Usually the COGS expenses are posted on a COGS expense account.

Hope that explains it. If not, don't hesitate to ask.


Setting the partsgroup together with seeding the database shouldn't be much of a problem: it only requires that you seed the partsgroup table as well as the parts table.... Uploading the pictures is the more difficult part, although even that is quite manageable.


The strategy I used to seed a parts table I had to seed is: create a temporary table in the database you want to seed the parts table in. Then upload the original data in that table. Create columns in the temp table to hold the IDs used in the parts and other tables. Then, use INSERT ... SELECT ...; statements to insert data into the parts and other tables until satisfied. As the last step, drop the temporary tables.


Hope that helps.


Bye,

Erik.

Erik,

Thanks for responding.  You got the two questions right.  I need to populate the parts table, and assign each part to a category (partsgroup) along the way.  My accounting background is rather slim.....
should new income and expense accounts be created?  Or, use existing (eg, Sales 4010 and Purchases 5010)?  There are no services at this point for the company.

I'd be happy to write it with you.  I'm also new to Perl; I've been using Python for years and was going to write the load script using a tool like SQLAlchemy.


Thanks.
Brian

What is the best way to insert an associated photo in the file_part table?  Meaning, is there a way of duplicating the upload feature? 
Looks like there are three account numbers that should be supplied.  How are these determined?

  inventory_accno_id integer,
  income_accno_id integer,
  expense_accno_id integer,

Am I correct to read at least two questions here?

1. How can I upload multiple parts (or maybe: how can I create an initially seeded parts table)?
2. Once I have a parts table filled, how can I insert the pictures belonging to these parts into the file_part table?


In order to be able to do (1) you indeed need to identify the accounts to book inventory, income and COGS on. These IDs correspond to the ID column from the 'account' table. If you intend to set up services, you don't need to fill the 'inventory_accno_id' column.


As far as the upload of pictures goes: that's a bit tough, because the data is encoded before it's sent to the database. You'd need to duplicate the encoding (I think it's base64, but not sure) and do the upload yourself... But maybe it's more practical that we write the upload script together to allow you to write a script to drive a web based upload to achieve the same purpose, much like the CSV uploads for gl accounts and some other items that I wrote for 1.4?


Bye,

Erik.
