Spending Limit Impacts Owned Corporation Supply Purchase?

I went to buy some supplies for a corporation (electric motors, because the market was deep in surplus).

I went to order 90 months of supplies, to take advantage of the low prices and got told that I'd hit my spending space limit.

Spending space should only apply to strategic stockpile purchases, yes? Or am I going to hit a problem when I own enough corporations that they consume more than 500B/month in feedstock because they won't be able to make their supply purchases?

Corporations have individual spending limits independent of your ceo limit. If you buy the supplies from your ceo it will use your ceo limit, so let the corps do the buying.

I am not sure what the Corp limit is but I have run into it before.

This was the first order I put in for this corp. If those per-corp spending limits aren't at least enough to buy a full stock of ONE supply, then they're too low.

Corporations have a spending limit.

buying 90 months of supplies is a lot.
Unrealistic.
A corporation taking all the money from the bank and putting it into supplies for 7.5 years?

I think the limits should apply or corporations will cause destabilisation of the market with unrealistic orders.

Pardon my bluntness, but if you want to talk about unrealism, let's look at some other features of the game, shall we? Like price caps/floors? Or the perverse incentives created by the way you implement the quality system? To call permitted activity (the game allows you to buy 120 months of supply) 'unrealistic' is just a lazy dismissal of a player pointing out a discrepancy in your design.

In support of my point, however, I believe you allow the 'unrealistic' 120 months of supply, because you recognize that we are playing a game, and sometimes players go on vacations and can't be at their keyboards. Letting them stock up a corporation before they go is just a design choice that lets your game appeal to people who can't spend 24/7 playing it - also known as 99.99% of your market.

Corporations can build up a 120 month supplies.
does not need to be in a single month. It is not realistic for the market.
it will also push the corporation into negative cash, loans and possible bankruptcy.

we had it all in the past.
we were then forced to put some limit to purchasing.

the limits are such that you can purchase much more than what the corporation is using each month.
