Purchase of fixed asset is shown under cash flows from investing activities as an outflow of cash because purchase of assets is an investing activity and it causes reduction of cash flow.
The cash derived from the sales would be the asset. While the term "cash sales" (as opposed to credit sales) may appear on an income statement or a cash flow statement in the plus column, the cash received would appear as an asset on the balance sheet or financial statement.

Additionally, there may be delays in processing certain transactions, leading to a lag in their appearance on your statement.
